Leaf Septoria? leaves more yellow than photo, and getting worse.

(BTW, I have NO idea why the word photo is in the title, nor what I meant to put there, but I can't seem to edit it! ptthh!)
My plants, growing outside, had been doing great this year, having less yellowing of leaves than ever before. I've fertilized it less than previous years, and I think that helped.

However, a few weeks ago, they started developing leaves with black spots, and then turned yellow and, if I didn't pull it off, it would die and drop off. We went out Saturday, and there were a few on each plant (both varieties: Girl Scout Cookie Extreme and Blueberry). then, went today, Tuesday, and the bottom half of most of them were almost ALL spotty, yellow, dying leaves! I took photos, but my old camera doesn't take sharp, up-close photos, so I'm posting the best, and hoping someone can help me identify it so I can fix it before it hurts them even more. I've been intending to post this for weeks, but had tooooo many things going on...sick dog, etc!

Anyhoo, thanks for your help. Maybe some day I'll have all my stuff in a row and be able to help you!

Pic sucks

I know/ I said it was bad.
but, do you have anything to say to help?
It's yellow leaves with black spots, and getting worse. I need help, not criticism on what I already know. Thanks

BTW, I realized what I meant by more yellow than the photo....the leaves are more yellow than the photo of leaf septoria.

that is leaf septoria i believe

first pic is my plant leaf,second is from a google search,a leaf infected with septoria,copper spray works

I have battled septoria for years with my outdoor grows. I spray with a copper fungicide every three or four days at dusk. I remove all infected leaves. Also helps with bud rot. I live in Florida and the humidity is outrageous. Good luck

thanks! The leaves start out pretty much like that. Then, the spots get blacker, and the leaves get yellower, then lighter yellow and die. It all happens pretty fast. I'll try the copper fungicide. I sure appreciate the help with identification so I have an idea what to do!

Good luck with yours!
